WATER COOLED SLIDE RAIL FOR REHEATING lFURNACES v-FileclfjJune 21 1928 Patented Mar. 1o, 1931 UNITED STATESl FRIEDRICH vCARL SIEMENS, I OFIBERLIN, GERMANY WATER-COOLED SLIDE RAIL FOR REHEATING FRNACES l Application led June 21, 1928, Serial No.

This invention relates to a further development of the water-cooled slide rail for relieating furnaces covered by the United States Patent No. 1,572,566. According to 5 the said patent the water-cooled supports of the slide rails, extend in the longitudinal direction of the slide rails and parallel thereto, that is, perpendicularly.

Now the present invention consists pri- -G marily in arranging'these cooled supports in a position differing from that given in the l afore-mentioned patent, at any convenient angle to the slide rails. This invention may be carried out in various ways. Thus for eX- l" ample the individual supports arranged one behind the other in the longitudinal direction of the slide rail, may be placed obliquely in such a manner that they areV inclined to o the rails on one side and the other alternate- C ly, for the purpose of protecting the rails against lateral thrusts. They may however alternatively be formed by tubes extending perpendicul arly tothe longitudinal axis of the M furnace, these tubes then being bent in varid ous ways to form the supports, the tubes being looped, UShaped, V-shaped or the like. This gives a better supporting of the slide rails against laterally acting thrusts, moreover a more convenient arrangement of the bends of pipes connecting the individualA cooling tubes of the supports, which in this arrangement must be arranged at the sides of thefurnace and not underneath the furnace, as in the United States Patent No. 1,5?2,566.

The accompanying drawings illustrate various constructional forms of the invention.

In all the figures, the furnace chamber a is shown in cross section, and the Watercooled slide rails extending in the longitudinal direction of the furnace chamber are indicated at b. i

Now in the constructional form according to Fig. 1, the Water-cooled supports 0 are placed obliquely in relation to the slide 'rails b, in such a manner that one support is inclined on the left and the other on the right alternately in relation to the said slide rails,

' rails at the sides, the supporting 4of the slide 'i 287,283, and in Germany June 27, 1927.

whereby a more reliable supporting ofthe rails against lateral thrustsis obtained.

In the constructional form shown in Fig. 2,'the` slide rails 'b are supported upon tubes c passing across the furnace-perpendicularly,55 to themythese tubes being'bent in the centre intofloops d', which'here form the actual supportsf Since in this casethe brickworkof the furnace also assists in carrying the slide struction. y l l In' the constructional form according to Fig. 3, the tubes@ carrying the slide rails are bent'outin the middle at e into the formv of a U jin suchv a manner that the two limits ofthe L!I serve yas carrying-supports for the tubes c, which at the otherend are supported in the brickwork of the furnace.

The constructional form shown in Figft, 6G is intended ffor" furnaces in which rather heavy ingots are to be heated.' rThe tube I0 whichis 'here likewise utilized for carrying the slide' rails b, is here bent intoja'n inverted -rfv U for each slide railythe further'isupporting by the brickvvorlrof the furnace, as adopted in the case of Figs. 2 and 3, being yhere abandoned. 'l Fig. u5"'difli'ersfrom Fig. 4 merely in the fact'thatv the inverted U-shaped 'supports fm of the slide rails arepulled out into an inverted V-shape." 'y `f 1"' The constructional form according to Fig. 6 is intended for a furnace for particularly long and heavy ingots',ffor which three slide 55 rails b are here provided. These slide rails may of course be carriedinl the same way as in Fig. 4 for eXample,but in the construcrailsby the tubes cmaybe of "lighter con- Cil tional formi shown in Fig. 6 the U-shaped supportsare theother way up, so that the 90 tube c may be supported at both ends by the masonry of the furnace. The U-shaped supports fare hereso closetogether that the slide rails Z) can besupported in the upper end ofthe slot between the two limbs of the U. 95 It is of course obviously possible also to design other construe-tional forms of the presentfinvention, as the figures included in the accompanying drawingsare merely given m0 by way of example.

What I claim is l. A water-cooled slide-way for reheating furnaces,V comprising the combination with horizontal tubing extending in the longitudinal direction of the furnace and constituting slide rails of tubular supporting members for the slide rails, said tubular supporting members extending transversely to and .also downwardly from the slide rails.

2. A water-cooled slide-way for reheating furnaces, as set forth in! claim 15 in which the tubular supporting members are inclined with their lower ends Von opposite sidesv of the slide rails.

3. A watercooled slid'eway for reheating furnaces, as set forth in claim l, in which the tubular supporting members are alternately inclined to opposite sides of theVV slide rails.

4. A wate-r-cooled slide-way for reheating furnaces, comprising the combination with horizontal tubing constituting slide rails. extending in the longitudinal' direction of the furnace of tubular supports for the slide rails, arranged in planes transverse to the VAlongitudinal axis of the furnace and 'corn-V prisingA horizontal bearing elements on which the slide rails rest and downwardly directed tubular limbs constituting supports for the horizontal bearing elements.
